Thanks for the question. It is currently not possible to play cards vs cards in this system. Cards are played individually and then resolve their action before the next can be played. You will need to wait for the v1.7.0 update happening in a few months where we enable Enemies to have their own Cards and Decks as well. Once that is available, it will be possible to use Custom Zones in order to have Skill Cards beat other Skill Cards like you are envisioning (both cards go to the same Zone, they are compared against each other and one Card wins out and resolves). Hope that helps :)
